Panel-mount Type Residual Chlorine Meter (Four-Wire Transmission)
HR-480 industrial residual chlorine meter takes sequential measurements of free residual chlorine, which is an indicator used in the inspection of the anti-bacterial properties of drinking water and swimming pools.
The sensor(RS-1) combined with uses a galvanic method with no drive section, making it highly maintainable, and producing stable measurements over a long period.
Free residual chlorine concentration: 0 - 2 mg/L
